This-invention relates to outside metal car roof wherein metal 'roof sheetsare connected along theiradj'acent margins by ridge seam?V covers upon which said roofslieets slue or, v

.-eiids'o'theridge seam covers ll and side oscillate so as to accommodate themselves automaticallyy to the distortions ofthe car The, prin-cipal object of the present inventionis aj strong and durable seam'construc-v tionk that will secure a sluing or oscillatory movement 'of the sheets about points located Y near'their adjacent margins. `Other objects f are simplicity Vand cheapnessof construction, compactness and economy of design andease ofassembly.V Y

The invention consists principally of theimproved ,seam construction hereinafter described; andl it also consists in the combinations and arrangements of described and claimed. l i In theI accompanying drawing, which forms part of this specication `and wherein theyoeciir, u

Fig.' 1 is a plan view of the ridge portion of an outside metal* car roof provided with a ridge seam construction embodying my 4invention; Y

Fig.V 2k isa vertical cross section `Vthrough' `said ridge seam' on line 2 2 in Fig. l; and

Fig. 3 is a bottom plan view of one of the ridge seam covers.

In the construction illustrated in theac companying'drawing, the metal roof sheets 4 rest on a woodenslieathing v5V, which is supported at the ridge on a wooden ridge pole 6. The metal roof sheets L kare arranged `in two rows, one on each side of the ridge, theV sheetson opposite sides of' the ridge being spaced apart; and the sheetson the same vside of the ridge are loosely Vpositioned between wooden'mullions or battens 7 arranged-transversely of the car and secured at the roof sheathing. *v

VThe side and the ridgemargins of the roof sheets 4L are provided with raise-d side and ridge marginal seam flanges or ribs 8v 'and 9, respectively.v Side seam covers or caps 10 of substantially inverted channelshaped section straddle the adjacent side seam flanges or'ribs 8 of the roofsheets and the battens 7 located therebetween.' Theadjacent ridge seam flanges 9 of said sheets are connected by means of inverted channelr shaped ridge seam covers or kcaps lll that partshereinatter 1 `vstantially midway of 'theY lengtlithereo'f, Y

preferably by rows of rivetsflS which extend Y parts wherever straddlesaidfridge seam tlanges'and Vhave outstanding base flanges l2that rest ori-'the body portions of said sheets insidev theV side Y. and ridge flanges thereotiv rlhe adjzment seam covers 9 are held in position on the car by means yofthe lusual-four-.way cornerk caps l 13 that; arefsecuredin position by lvertical bolts 14, whichal'so secure the running board: 'f

. Secured to the Linder side( ofjtheUtop-i'of' eachrridgeaseam cover l1 isra pivot'piecev or clip` 1,5, whose cross-sectional,shape V comprises two longitudinally extendingdownwardly opening side marginalgrooves or channels 16 that are separated by an up-wA wardly openingfmiddle Channel 17.1`Thefgroovedl-pivot members or clips I15 are se-V cured to the ridgeseam cover, at VpointsSub'i-l through each of the channelslrandA thus grooves or channels 16 of the pivot pieces or prevent spreading thereof. The-laterally f' spaced. downwardly opening side marginal' clips 1,5 extend!longitudinallyof the ridge seam covers-l1 and are adapted Vto-l straddle y the middle portions of the spaced ridge seam 'flanges 9`of'oppositely arrangedroof sheets.

They channels 1.6 of the pivot Vmembers are made wider at theirends than at .their middle, preferably by reversely curving or bowl ing the side walls of said channels :trointhe-ir middle towards their ends. s the narrow middle portion Vof the downwardly opening groovesl corresponds to the width of the ridge seam-flanges 9 of the sheetswhereby said grooves snugly embrace said flanges and thus prevent relative or jointbodily movement of saidsheets cross-N `wise of the! car. K oi thel downwardly opening channels lr6 from By reason ofthe widening weaving of the car frame inservice.

One of the principal advantages of the foregoing construction is that-it permits theV pivot pieces or clips to `be lreplaced when they become worn `or .damaged` 'in service.

The width of v Another advantage is that said clips serve to reenforce and s tiifen the ridge seam covers against forces tending to distort said seam covers or clips and thus interfere with the sluing movement of the roof sheets.

My invention is not restricted to the precise forms and arrangements shown and described. Y Y

What I claini is:

l. A flexible'car roof comprising roof sheets spaced apart along their adjacent inargins and having raisedribs extending along said margins, a seam cover straddling the ribs Vof the adjacent sheets, and a member secured to said seam cover and straddling eac-h of said ribs.

2. A exible car roof comprising roofv sheets spaced apart along their adjacent marginsand having raised ribs extending along said margins, a `seam cover straddling the ribs of adjacent sheets, and a member rigidly secured to said seam cover and having contact with bothsides of each. of said ribs for a portion yof their length only..

8. A flexible car roof comprising roof sheets spaced apart along their adjacent inarginsand having raised ribs extending along said margins, a seain cover straddling the Y ribs of adjacent sheet-s, anda pivot ymember secured to said searncover and having downwardly open-ing groovesy formed therein adapted to straddle the ribsof adjacentv sheets, said'groovesbeing Wider at the ends than at the middle.

l... A flexible ear roof comprising 'roof sheets spaced apart along their adjacent inarginsf and having raised 4ribs extending along saidy margins, a seam cover straddling the ribs of adjacent sheets, andl a pivot clip secured toltheund-er.v side of the top of said seam cover and being provided With .downwardly opening grooves Which straddle the ribs of adjacent sheets and engage both sides of each of said ribs for a portion of their length lonly.V l

5. A flexible. car roof comprising roof sheets spaced apart along their adjacent margins and having raised ribs extending along said margins, a sean-i vcover straddling the ribs of adjacent sheets, and a'pivotclip l0- cated beneath said seam cover and having downwardly opening grooves .thatstraddle i the r'bs of adjacent Vsheets and engage both Ysides'of each of said ribs for a port-ion of.

their length only, said clip being rigidly secured to said seam cover by fastening meinbers located adjacent to each of said grooves.

6. A seam cover for a car. roof,lsaid seain cover being of substantially inverted channel-shaped section, and a clipv secured to said-l seaml cover and having laterally spaced downwardly opening' grooves extendingV longitudinally thereof.

7. A seam cover for a car roof, said seam Vcover being of substantially inverted chan` nelshaped section, and aelip secured to said seani cover vand havin-gql-aterally spaced grooves therein that'are of greater Width.
